Error in Microsoft C

[Thomas Otake /ADVISOR Clay]

A friend of mine, working with Microsoft C, ran into a situation which
made her go nuts. When compiling a program the following error message
was shown:
   Invalid object module
Since I don't use Microsoft C I wasn't much help and am hoping somebody
out there could tell me what is wrong or what the cause of such an
error might be.

Thanks in advance. If possible replies to my E-mail address are apreciated
since I don't read the news too frequently.
